I am the owner of a 2003 Pontiac Sunfire and I recently had a problem of the high beams not working, I simply cut the wires on the back of the headlight and wired them to a switch purchased at the auto parts store, no problems since, and nothing else is wrong.

I own a 2000 Pontiac Sunfire. There are a lot of issues with this car that I have noticed.

I was one of the first ones to have their sending unit go (this was where the gas gauge was not reading properly). GM replaced it once under warranty, but it went again. GM wouldn't replace it for the second time, even though they knew that it was a problem, so I just kept putting the additive in the gas tank, and it seemed to solve the problem.

Also, I had the problem with the DRL lights not working. That was due to the wiring harness behind the front bumper (very expensive repair). I was lucky I knew someone that worked at GM who claimed it under warranty, even though I had over 100000 kms. I also had the blower resistor and the blower motor go.

And just recently, my car stalled on the highway (traction control light and the battery light came on) and the car had no power, but it only did that once, and started to work fine after I started the car a few times, so I don't really know what the problem is.

Now my coolant low light is coming on and off, but there is enough coolant in the car. Has anyone had these problems, with these idiot lights coming on and off?

1999 Sunfire - Electrical gremlins.

Boy, I thought I was in a boat of my own until I stumbled across this website. I'm just thankful I have a pre-2000 Sunfire so I don't have to worry about the driving light issue, thought the turn signal problem is driving me nuts.

Turn signals go on and stay on. I must manually flash the lever or risk being rear ended by a non alert idiot bearing down on my rear bumper. Oh, did I mention this happens whenever it wants, sometimes works, sometimes it is both sides other times just one. I can't figure out it out. What I have done that seems to have helped just a little bit (problem actually went away for like five weeks) was to remove that di-electric grease in the bulb socket with some rubbing alcohol and Q-tips. The leads looked corroded and I think that grease is actually trapping moisture in. Just a theory.

Same problem with everyone else with the blower, I'll try to tackle this repair myself this weekend.

AC doesn't work, won't even take a charge. Garage says that is already at maximum pressure and it won't take. This being good because seals should be fine. Then it might be issue with the evaporator or blower doors. Any suggestions?

My newest beef now if the gas gauge. I figure I can go about 240 miles or so on a full tank. The needle slowly goes down to about a 1/2 - 1/3 tank like normal and then goes back up. The gauge will actually read full when the tank is on fumes. What the heck!

Any help suggestions whatever badgrhockey@gmail.com.

I own a 2000 Cavalier. I have have similar DRL problems mentioned. The only difference is that the headlights do not work...period. All other lights work...ie...amber front lamps and rear lights. When I turn the car on, the DRL indicator light flickers and the service light turns on. If I pull the high beam lever nothing happens. I do not think it is the headlight switch assembly. I zeroing in on the DRL relay found in the fuse box in by the driver side door. Any suggestions? I'll check the wiring behind the headlights tomorrow. My e-mail is gwl1972@yahoo.com. No spam please.

I have a 2000 Pontiac Sunfire and have had it since it had 10,000 miles. I have had the most random issues with it, much like the ones mentioned above; however, I am not having light issues. There isn't much that is electrical in my car. My heat/AC will not work on intensities 1,2 or 3. I thought to myself, how can this die in a car? It's not wear and tear?! Well thanks to everyones comments I figured out what that was.

My car has stalled twice, once at an intersection while I was hitting the brakes. The other time, I was just cruising maybe 35/40 mph. My transmission sounds like it has issues. It is loud when I switch gears. I have kept up with the transmission fluid and filter since I bought it.

My trunk is broken. It won't open. That happened pretty early into it. GM fixed it under warranty, but it broke again right after 60k :\

Cd's have gotten stuck in the CD player. They come out half way sometimes. This could have been self-inflicted.

Anyone have ideas on the stalling? That's kind of important!

I forgot to include that my engine overheats while I am stopped. I have checked the thermostat, the cooling fluid is not leaking and it is clean.

I am the upset owner of a 2000 Pontiac Sunfire.

I have had many of the problems as you all have stated.

The wiring all happened under warranty, and after the 2nd time, I made them replace the wiring front to back. Since then (knock on wood) I haven't had those problems.

The a/c resistor is also a problem, but I finally took it to a mechanic who actually takes pride in his work, and he told me that now the issue is the cover for the a/c fan is off slightly, and the fan blade hits it from time to time, thus creating a spark and shards of metal that go all over, and that blew out the fuse within. He fixed the fuse for free, and said to bring it back in when I had time to reattach and properly weld the cover at a very reasonable price.

Here is my big problem; I have now replaced the clutch, $1350.00, the windows don't fit the door (I saw someone say they felt like they were driving through a wind tunnel, it's because the glass is not made to proberly enclose in the frame. The window sticks going down and is a pain to put back up, you have to play with it. The drivers side door lock is seized, (love the Canadian weather that they sure seem to know how to build for) and my car keeps dying. NOT IMPRESSED!

I have been having similar problems with my 2002 Sunfire.

Most everything seems OK when I drive in the daylight, but at night when I turn the headlights on, problems start. The headlights are dim, the needles on the gauges keep going up & down, all kinds of warning lights on the instrument cluster come on, and it says "Error" where my odometer reading normally is. Also the DRL turn signal indicators flicker.

Is this because of the problems everybody has been having with the headlamp wiring harness? Does anybody know of a kit for repairing/replacing the wiring harness? I would like to repair/replace it myself to save money.
